I'm not the OP or the parent post's author; however, pre-covid I'd give the usual answer of just join meetups, attend in person, follow the gang to the neighborhood bar or coffee or wherever they go, make friends, birds of a feather, etc. Post-covid, that scene seems non-existent to me. Being an introvert, it was certainly not a game I understood intuitively, outside of the fact that the groups were so small in my city as to be harmless to someone like me with the social skills of a loner. FWIW though, every single gig I've had for twenty years was among friends-of-friends with a common thread, typically art, music, science (OS, PL, DB), or culture (motos, bikes, skateboards).
